hmmm, I don't think that 15 matters that much after a Belly Drum.
Did you did the Emerald cloning trick like I said? It must be tough to erase and hatch that thing legit. If I were you, I'll use a fast hatch code.
If you get anything more delicious... like a better attack IV, I like a slice, but I like to trade for this if you want any of my XD resets.
